Head Porting basics

Is into the water or open air?

Is that on all ports or just one?
still good numbers, but what are the .200-.450 lift #'s?
So looking back and knowing now what it takes, not too hard huh?

I love these heads.

The hole was in Open air or oil side.

All my tests have been at .100 increments

56/129/193/238/265/267 this is what it is right now(representative of picture above)

Before i messed up the seat or, my best numbers were.
61/131/193/240/267/264

I have only done one intake port all the rest still are at my 15 year a go bowl porting state.
